Answer:
- x/45 = 9 m/30
- x = 13.5 . . . meters
Step-by-step explanation:
In similar triangles, corresponding sides are proportional. This lets us write an equation involving x. Sides adjacent are proportional to sides opposite the vertical angle.
x/45 = 9/30
__
Multiplying by 45 gives the solution:
x = 45(9/30) = 13.5 . . . meters
Answer:
y = 20 x = 6
Step-by-step explanation:
1 (3x+ 2y = 58 ------------> -3x + -2y = -58
1x + 2y = 46 --------------> 1x + 2y = 46
____________
-2x = -12
-----------------
-2x -2x
x = 6
3(6) + 2y = 58
18 + 2y = 58
-18 -18
------------------
2y = 40
----- -----
2y 2y
y = 20
